Title: Improvements relating to the construction of motor vehicles
IPC: B60K5/10
Filed: 1954-08-03
Abstract: 761,500. Motor vehicles. DAIMLER-BENZ AKT.-GES. Aug. 3, 1954 [Aug. 3, 1953], No. 22559/54. Classes 79(3) and 79(4). In a motor vehicle having an engine, clutch and change-speed gearing unit 6 resiliently supported at three points 8, 11 on an end cell. which has a planar connection to the adjoining cell 1, the end cell frame 4, 5 has a part 9 projecting beyond the plane of connection and carrying the unit support 11. As shown, the part 9 is releasably connected at 10 to the frame member 4 ; the connection 10 may be resilient and the part 9 may be of spring steel. The part 9 and unit 6 project into a tunnel 2 in the adjoining passenger carrying cell 1 of the vehicle, the change-speed gearing 7 being releasably connected to the engine and to a cardan shaft 3 connected to differential gearing (not shown). The planar connection between the adjoining cells is either rigid, for example formed by bolted flanges, or pivotal. By releasing such connection and that between the shaft 3 and gearing 7, the end cell is readily detachable. By releasing the connection 10, that between the shaft 3 and gearing 7 and that between the engine and gearing 7, the gearing 7 can be removed, a spacer being provided between the engine and the frame member 4.

IPC: F01D21/16
Filed: 1960-06-30
Abstract: 982,292. Turbine stop gear. FAIRFIELD SHIPBUILDING & ENGINEERING CO. Ltd. June 29, 1961 [June 30, 1960], No. 22866/60. Headings F1K. and F1T. A turbine trip gear includes a feeler 15 arranged to be displaced following excessive axial displacement of the turbine shaft 10 resulting from wear of the turbine thrust bearing, motion multiplying means associated with the feeler and a loaded valve 18 adapted to be held in a normal setting by a trip element 21 movable with the motion multiplying means, the construction being such that displacement of the feeler is accompanied by movement and ultimate withdrawal of the trip element and by displacement of the valve to bring about stoppage of the turbine. The trip gear may be carried by a cover 12 associated with the thrust bearing of the turbine being secured to the turbine casing, the bearing including a thrust collar 13 on the turbine shaft which collar is engaged by circumferentially spaced thrust bearing pads 14 and is engageable with the feeler. The gear may be arranged to operate in association with a turbine overspeed or other governor normally of centrifugal type incorporated in a pressure oil system from which release of pressure brings about closure of a stop valve of the turbine. Thus the valve 18 of the gear is interposed in the pressure oil system and so devised that when the gear is tripped the oil is by-passed from the system and drained into a sump within the turbine casing.

Title: Improvements in or relating to talking films
IPC: G11B7/00
Filed: 1930-08-06
Abstract: 360,940. Optical sound-recording and sound-reproducing apparatus. KONEMANN, H., 4, Gereonstrasse, Munster, Westphalia, Germany. Aug. 6, 1930, No. 23549. [Class 40 (iil.] Sound is recorded on a film by using two light sources, the intensity of which is modulated in accordance with the sound, in such a manner as to produce side by side on the film two records which are 180‹ out of phase. Reproduction is effected from these records by causing them simultaneously to influence a light beam acting on two photo-electric cells, these being preferably used in conjunction with a push-pull amplifier to operate a loud-speaker. It is stated that with this arrangement, errors produced by fogging of the film or curvature of the photographic characteristic curve may be avoided, and a weaker average exposure may be given to the film. The recording apparatus shown in Fig. 1 comprises two lamps L<1>, L<2> supplied with direct current from the mains through choke coils D<1> D<2>. Microphone currents are superposed through a transformer T on the currents in the lamps, the connections being such that as the current in one lamp is increased that in the other is decreased. By means of a suitable optical system C, S, O, two sound records which have a phase displacement of 180‹ are thus produced at a, b on a photographic film F. Fig. 3 shows an apparatus for reproducing sound from such records. Light is transmitted from a lamp L<3> through both records a, b on the film F simultaneously, and the two modulated beams thus produced are reflected on to photo-electric cells Z<1>, Z<2> respectively. These cells are connected symmetrically in known manner with a system of valves R<1>.. R<4>, so that the amplified currents are combined in an output transformer and operate a loud-speaker L. As an alternative, the currents of the two cells could be combined by means of a transformer and transmitted to an ordinary amplifier. Reference has been directed by the Comptroller to Specifications 329,405 and 332,197, [both in Class 40 (ii), Phonographs &c.].

Title: Processes for the preparation of thickening compositions and lubricating greases
IPC: C10L7/02
Filed: 1953-08-26
Abstract: Lubricating greases comprise oils thickened with a composition made by mixing an oil, a surface-active agent and a hydrogel of an inorganic colloid and spray-drying the mixture.  Gels referred to are amorphous substances such as inorganic oxides, hydroxides, sulphides, carbonates and phosphates, such as silica, alumina, magnesia, lime, copper sulphide, calcium sulphate and manganese phosphate or mixtures thereof; and crystalline substances such as natural and synthetic clays, for example montmorillonites such as sodium, potassium, lithium and magnesium bentonite, Wyoming bentonite, hectorite and saponite, attipulgite, zeolites and fuller's earths.  The surface active agents may be cationic, anionic or non-ionic; suitable agents are described in Specifications 672,650, 683,969, 685,146 and 703,169, and may be, for example, stearic acid; the hydroxy polyamines, such as those formed by partial amidization of the condensation products of epichlorohydrin and ammonia, for example by reacting with tallow fatty acids; polymeric silicones such as those formed by condensation and polymerization of dimethyldichlorosilane; and alkyd resins.  Oils specified are mineral lubricating oils or synthetic lubricating oils such as cracked wax olefins, polymerized lower olefins, aliphatic esters of dicarboxylic acids, such as bis (2-ethylhexyl) sebacate, phosphorus esters such as tricresyl phosphate, trioctyl phosphate and the corresponding phosphonates, phosphinates and phosphine oxides, oxyalkylene polymers, such as propylene oxide polymers, copolymers of ethylene and propylene oxides, trimethylene glycol polymers and esterified or etherified derivatives of such polymers, and halogenated organic compounds such as hydrocarbons, for example fluorocarbons.  The spray-drying may be carried out at 50-100 DEG  C.; residual water may then either be removed by spray or oven drying, or may be left in the composition until a final product is formed therefrom.  The composition may also contain, with or without water, volatile liquids such as alcohols, ketones and esters, for example methanol, ethanol and acetone.  The composition may be homogenized prior to spray-drying and pre-milled after spraying.
